【摘要】 由于Cyber-shot品牌的手机存在产品等级的明确划分，当今市场上，针对手机而言的照相功能及其单一化，甚至有的都没有最基本的卡片式相机的功能，例如ISO调整等功能，针对A2平台手机K850和C905，借助拥有SONY专利的优秀相机Cyber-shot影像系统的优秀软件平台,加之采用第一代大尺寸1/2.3的Exmor传感器的旗舰照相手机C905的优秀硬件平台，采用I2C Command语言实现对该影像系统的开发，主要在于针对相机驱动的研究和开发，让某些只有在单反相机上拥有的功能得以实现，来弥补手机上照相功能少，微距过曝，远距曝光不足，成像锐度不够，成像色彩不够真实等缺陷。该设计通过对寄存器参数以及对应功能的研究、手动功能实现的研究、色彩系统技术研究、闪光系统技术研究，形成一整套基于I2C Command语言的语法体系系统，并再在该基础上对其中控制系统进行开发。该控制系统的开发涉及闪光系统、对焦系统、色彩系统、曝光系统等，主要整合了闪光与对焦系统，开发了防止一种近距离对焦闪光过度曝光，而远距离对焦闪光曝光不足，以及配合色彩系统采取色彩校验的方式的智能控制系统。同时将曝光系统增加了手动调节功能，针对自动曝光设置了曝光锁定功能。其次针对夜景模式提出了Enhance Mode，利用长快门与低感光度的配合，目的在于增强低光照条件下夜景的拍摄质量。最后针对摄影学原理设计了冲突设计，防止了相关参数之间的重叠与覆盖。本课题研究的目的在于改善手机的拍照功能单一的现状，利用基于搭载Cyber-shot影像系统的A2平台手机进行相机驱动研究与开发，利用I2C Command语言进行设计与实现的方法，增加手动控制和智能控制来强化手机拍照功能，以达到满足对曝光的智能控制以及多种参数的手动控制的结果，通过智能控制与手动控制相结合的方案，完成全面的相机控制。课题要求对驱动的整体结构的分析研究得出一套技术方法，从而在该基础上进行开发，以达到在手机上实现部分单反相机的功能以及对操作速度的提升。更多还原

【Abstract】 Since Cyber-shot branded phones there is a clear division of product grades, on the markettoday,for cell phones,camera function and single,and some are not even the most basic card-camera features such as ISO adjustment and other functions,A2platform for mobile phonesK850and C905,the aid has outstanding patent SONY Cyber-shot camera imaging systemexcellent software platform,coupled with the use of first-generation large-size Exmor sensor1/2.3’s flagship camera phone C905excellent hardware platform,using I2C Commandlanguage for the development of imaging systems,mainly for camera-driven research anddevelopment,so some only in SLR cameras have features to be implemented to compensatefor camera function on the phone less overexposed macro,telephoto exposure lack of imagesharpness is not enough,not enough true color imaging and other defects.Through the study of the design parameters and the corresponding function registers,thestudy manual functions to achieve,color study system technology,flash technology researchsystems,the formation of a set of grammatical system of systems based on I2C CommandLanguage,and then on the basis of which the control system development.The development ofthe control system involves flash system,focusing system,color system,the exposure system,mainly integrated flash and autofocus system,developed to prevent the kind of close-focusflash overexposed,underexposed flash and remote focus,as well as with color intelligent colorcalibration system to take control of the way.The exposure system while increasing themanual adjustment function,set the exposure for the auto exposure lock function.Second nightmode made for Enhance Mode,use long shutter with low sensitivity with the aim of enhancingthe night under low light conditions shooting quality.Finally,the design principles of conflictphotography designed to prevent overlapping and covering the relevant parameters.The purpose of this research is to improve the phone’s camera features a single situation,the use of image-based system equipped with Cyber-shot phone camera’s A2platform drivenresearch and development,the use of I2C Command Language design and methods ofimplementation,increased manual control and intelligent control to enhance cell phone camerato achieve the results meet the exposure manually controlled intelligent control and a varietyof parameters,through intelligent control and manual control program combines complete acomprehensive camera control.Issue requires analysis of the overall structure of the drive todraw a technical methods,which developed on that basis,in order to achieve to achieve someSLR camera function on the phone and on the operating speed of the upgrade.更多还原
